10 Claims.

This invention relates to electrical illuminating devices, and is particularly directed to electric chandeliers.

An object of this invention is to provide a de- 5 vice of the character described, comprising a base and a set of lamps wired in series circuit, the construction being such that the lamps may be removably mounted on the base, whereby the base and the set of lamps may be sold individually and readily assembled, without requiring attaching devices, tools or any particular mechanical skill.

A further object of this invention is to provide a device of the character described, comprising a flexible base on which a plurality of candle simulating members having electriclamps thereon are mounted, the base being adapted to be pressed into greater or less curvature, and means being provided for holding the base in any adjusted shape thereof.

A further object of this invention is to provide a neat, attractive decorative electric chandelier of the character described, which shall be comparatively inexpensive to manufacture, comprise few and simple parts, be easy to assemble or adjust into various shapes and which shall nevertheless be practical Vand efficient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

In the accompanying drawing, in which is shown one of the various possible illustrative embodiments of this invention,

Fig. 1 is a front perspective view of a chandelier embodying the invention;

Fig. 2 is a top plan view of the chandelier shown in Fig. 1;

Fig. 3 is a rear elevational view of the structure shown in Fig. l;

Fig. 4 is a cross-sectional View taken on line 4 4 of Fig. 3;

A feature of the invention is that the base or mounting member for the candle simulating members may be adjusted so as to change the shape of the device;

Fig. 6 is a top plan view of the device showing the base adjusted to a shape different from that shown in the other figures; and

(C1. 24o-1o) Fig. '7 discloses a modified form-cf the candle holder. Y

ReferringA now in detail to the drawing, I0 designates a chandelier embodying the invention comprising afbase I2 preferably made of resilient sheet metal and having a lower edge I3.V The upper edges of the base I3,are stepped, forming a top edge I5, symmetrical lower edgesl I6 on opposite sides of the top edgel I5, still lower edges Il and still lower edges I8. The portion I9 of the base above the edges I5 is provided with vrearwardly curved, substantially cylindrical extensions 2D. Said extensionsl 2@ may be formed by merely cutting the edges'IG inwardly sufficiently to provide strips or bands which may be bent into curved shape.

'Ihe base below the edges I6, I'I, and i8 is likewise formed at the ends thereof with inwardly curved cylindrical portions 2Q. All of these portions 20 .are not entirely closed, to provide spaces 2l between the end edges thereof and the body of the base I2, for the purpose .hereinafter appearing. The lower: edges of the cylindrical portions 20 may be formed with inwardly extending tabs 20w preferably cut from the metal thereof, and

bent inwardly. Y

Adjacent the'bottom edge I3, the outer ends of the base I2 are formed with rearwardly extending strips'ZI, bent Cutwardlyat the outer ends 25 thereof to-form feet. An extensible in`- terconnecting member 2'I serves to interconnect the portions 24. The member 2'! may comprise a pair of strips 28 and 29 disposed in a vertical plane and having the inner ends'3il and 3| thereof in overlapping relation. The portion 29 may be formed with a plurality of spaced openings 30, and ther portion 28 may be formed at the inner end thereof with a foot'32 adapted to be received within one of the openings 39.

A bolt 34 passing through an opening 35 in the member 28 extends through another opening 30' in member 29 for clamping the members 28 and 29 together. Thus the length of the member 21 may be adjusted by removing the bolt and changing the relation between the members 28 and 29. Thereafter, the bolt may be replaced. Upon shortening the member 21, the base I2 becomes more curved. The shape of the base may thus be readily changed to increase or decrease the r curvature thereof.

As shown in Fig. 6, the base maybe straight insteadofA curved, the portions 24 of the base being interconnected Vby `a connecting member 21a riveted at one` end 2lbl to' one of said portions and having openings 2'Ic adjacent the other end, one of which receives the other of said portions. By engaging the portion 24 on the right of Fig. 6 with an inner opening 2'Ic, the base may be pressed into curved shape and retained in such shape. It will be noted that the contact of the bottom edge I3 of the base I2 and the connecting member 21ar with the support on which the member I0 rests, serves to hold the base in upright position. The member 2'I further serves to make the base more rigid.

There may be assembled with the base, a lighting outfit 40, comprising a plurality of tubular candle simulating members 4I, each having at the upper end thereof a lamp socket 42 to which a lamp 43 may be screwed. The sockets 42 may be interconnected by wiring 44 passing through said members 4 I, in series circuit and connected to anA attachment fitting 41. The lighting outfit 4D may be readily mounted on the base I2 in the manner hereinafter explained.

The wires adjacent the lower ends of the candle simulating members 4I may be first passed through the openings or spaces 2| between the cylindrical portions 20 and the body of the base, and the lower ends of the candle simulating members then frictionally pressed into said cylindrical portions. 'Ihe inwardly extending tabs Za serve as stops to limit downward sliding movement of the members 4I Within the cylindrical portions 20.

A dominant feature of the invention is the provision of a base and a series connected lighting outfit including the candle simulating members 4I which may be readily assembled on the base without the necessity for fastening devices, tools or particular mechanical skill. Furthermore, the shape of the base may be quickly and readily changed to suit the taste of the user.

In Fig. 7 there is shown a candle holder 20h, similar to the cylindrical candle holders 2U except that the same are bent to overlap the upper edge of the stepped portions of the base I2. With this construction, as the candle simulating member 4I is inserted, the bottom edge thereof will contact the upper edge of the base, thus rendering it unnecessary to form the tab 20a for limiting sliding movement of the candle simulating member.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing, is to be interpreted as illustrative and not in a limiting sense.
